Look South! 40% chance of aurora in next 24 hours

(Posted 23 June 2015) Missed this morning’s aurora? To be honest, I think most people who knew that one was likely to occur also did. I looked around midnight then had to head off to bed so I was clear headed for work. A colleague looked around 3 am and saw nothing. Finally after 5 […]

Planetarium presentation for Canberra Astronomical Society

(Posted 17 April 2015) Last night, I ran a short session in the planetarium for members of the Canberra Astronomical Society as part of the April general meeting programme.

Moon Phases pre/post test photocopy master

Comparison image of giant sunspot AR2192 with Earth. Summary …. it’s really big!

Take for instance, the giant sunspot AR2192 currently located on the Earth facing […]
